Organismal level

living things

Axial region

axis of the body : head, neck, and trunk.

Appendicular region

the appendages or limbs (arms and legs)

Dorsal hollow nerve cord

Core vertebrate structure running along the back that develops into the spinal cord and brain.

Notochord

Core vertebrate structure that provides axial support and develops into the vertebral column.

Pharyngeal pouches

embryonic structures in vertebrates that become gills in fish and give rise to the throat and ear as humans

Parietal serosa

Outer layer of the serous membrane lining the walls of internal body cavities.

Visceral serosa

Inner layer of the serous membrane directly covers the external surface of visceral organs.

Serous fluid

Thin fluid is produced that reduces friction as organs move

Retroperitoneal organs

Organs located behind the peritoneum (kidneys)
